  Design and synthesis of conformationally-constrained MMP inhibitors

  摘要：

  A novel series of conformationally constrained matrix metalloprotease inhibitors was identified. The potencies observed for these inhibitors were highly dependent upon the substitution pattern on the caprolactam ring as well as the succinate moiety. (C) 1998 Elsevier Science Ltd.

  Disclosed are anti-inflammatory agents, antiallergic agents, particularly prophylactically and/or therapeutically effective drugs for type I and/or IV allergic conditions, and further pharmaceutical drugs for prophylactically and/or therapeutically treating bronchial asthma, atopic diseases, etc. The inventive drugs comprising a prophylactically and/or therapeutically effective amount of a hydroxamic acid derivative are active in the prophylaxis and/or therapy of allergy, especially type I and/or IV allergy, etc. The drugs are active in prophylactically and/or therapeutically treating inflammation, rhinitis, conjunctivitis, bronchial asthma, atopic diseases (including dermatitis, enteritis, etc.), or allergic gastroenterocolitis (allergic inflammation in digestive tract). The application of such drugs leads to (A) reduction of cells (such as lymphocytes, neutrophils, mast cells, eosinophils, basophils, macrophages and monocytes) at a diseased site, and/or (B) alleviation of inflammatory symptoms caused by migration, infiltration or accumulation of cells (such as lymphocytes, neutrophils, mast cells, eosinophils, basophils, macrophages and monocytes) to (or at) the diseased site, (C) inhibition of pathophysiological functions in cells (such as lymphocytes, neutrophils, mast cells, eosinophils, basophils, macrophages, monocytes, Langerhans cell and dendritic cells), and/or (D) reducing the blood level or inhibiting the production, of antibodies, especially IgE. Accordingly, the drugs are useful in the prophylaxis and/or therapy of diseases, disorders or ill conditions at the site.

  本发明公开了抗炎剂、抗过敏剂，尤其是对 I 型和/或 IV 型过敏症具有预防和/或治疗效果的药物，以及用于预防和/或治疗支气管哮喘、特应性疾病等的进一步药物。包含预防和/或治疗有效量羟肟酸衍生物的本发明药物在预防和/或治疗过敏症，尤其是 I 型和/或 IV 型过敏症等方面具有活性。这些药物在预防和/或治疗炎症、鼻炎、结膜炎、支气管哮喘、特应性疾病（包括皮炎、肠炎等）或过敏性胃肠炎（消化道过敏性炎症）方面具有活性。使用这类药物可(A)减少患病部位的细胞（如淋巴细胞、中性粒细胞、肥大细胞、嗜酸性粒细胞、嗜碱性粒细胞、巨噬细胞和单核细胞），和/或(B)减轻细胞（如淋巴细胞、中性粒细胞、肥大细胞、嗜酸性粒细胞、嗜碱性粒细胞、巨噬细胞和单核细胞）迁移、浸润或积聚引起的炎症症状、(C) 抑制细胞（如淋巴细胞、中性粒细胞、肥大细胞、嗜酸性粒细胞、嗜碱性粒细胞、巨噬细胞、单核细胞、朗格汉斯细胞和树突状细胞）的病理生理功能，和/或 (D) 降低血液中抗体，尤其是 IgE 的水平或抑制其产生。因此，这些药物可用于预防和/或治疗该部位的疾病、失调或病症。
